Megabus London Tours

Ok thought some might be interested in this. Especially maybe if you have overseas guests?
Stumbled across it in SLP.
Megabus London Tours.
I've just booked 2 seats on this. Total cost with 50p booking fee, £4.50
The tour is 1hr 55mins
With the other london tours cheapest being around £26 per person. Makes it a bargain in my book. Has some excellent reviews on trip advisor.

You should try it. It was really good. Makes sense to do it now before it gets too well known. We got there too early. So would have been in time to get the earlier bus. That left with only one passenger. And it doesn't stop anywhere else.
